Hey wrench benders,

I don't like paying $30 USD for an air filter. I'd pay more for a K&N because of course they are quite durable and can be cleaned many times. I do not however want to change the airflow/gas mileage characteristics of the stock setup.

Ideally I'd the like "performance" of the stock filter with the long service life of the K&N. I have used K&N filters in other machines before and in every case they used more fuel than with a stock filter. I don't want to do that to my Strom, even if it means buying obscenely overpriced OE style filters on a regular basis.

What do you think?

MWValley,

Keep spending the 30 bucks on the OE filter. How often are you changing your filter out? Are you doing a lot of dirt road riding that requires you to change out the filter much quicker than the recommended intervals? Personally, I think spending the $$ on the OE filter is the best option. Some things are worth the extra bucks.

The K/N filter works well enough I suppose but to use it and then clean it properly one must have the work area and such. Apartment dwellers such as myself with no facilities are probably better off with the stock filter. Less mess and frustration in the long run.

Not to defend the K&N but "a work area" to service an air filter? WW, there really is nothing to it, all you need is some running water. Spray on the cleaner, allow to soak for a minute and then rinse. Once its dry, spray on the filter oil and re-install it in the bike. Really, a pretty simple operation.

MWValley, I'm curious of your increased fuel use. I've run BMC and K&N, reusable filters in various vehicles and never experienced increased fuel use.

The discussion about these filters is usually about their filtration qualities and the amount of material they allow to pass through to the engine.

Heavy, my only work area would be the kitchen sink and I wouldn't want to be flushing cleaners and old oil from the filter down into the drain. Even if I contained it all and disposed of it properly I still have a job that I don't want to do. Call me lazy if you want, I don't mind. The factory filters are easier to handle and the number of times it is changed won't be a financial hardship. If factory filters are a financial hardship then I can't afford to keep the bike and it will go to a new home. That's my story and I'm stickun to it. ... Ride On...

WW, I understand what you're saying. I guess I was just trying to get across that cleaning the filter is no real big deal.

On another topic, I managed to get out and put some miles on my new Strom. Man, the more I ride it the more I love it. I've got just over 600 kms now. Not much but not bad for 2, actual, riding days. Once the temps start staying above freezing it'll be that much better.

In regard to the K&N filter thing, I've installed them in among other vehicles a 1988 ZG1000 (Concours). Without changing anything else, the gas mileage went from a long-established 45 to about 40 or a little less. It could be my imagination but I think the engine did pull harder especially in midrange rev numbers. But the stock motor setup was plenty strong. I rode that bike for 7 years so having a "clean and reuse" filter was well worth the money but I don't know how much it cost me in fuel. In the 5 years that filter was in the airbox, I think the difference cost me as much as a pile of OEM filters.

I used several K&N filters from the late 70s to early 90s, but, frankly, didn't notice a difference in performance, just increased induction noise.

I didn't notice any drop in mpg when I switched to K&N on my otherwise onmodified Strom. However, when I remapped via a Yosh box, I went from 48-49 mpg to 39-40 mpg (cold weather) and 43-45 mpg (warmer weather). I enjoy the K&N b/c of it's long life, easy cleaning. Just wish it was easier to get to :?

Stromette just put in a K&N when also changed plugs, did TPS & TBS. Being mechanically declined I could not begin to guess which one is responsible for an INCREASE in gas mileage. All my bikes run w/K&N. With the mileage I put on it makes $ sense. Plus I find it easier to recharge the K&N than obtain a stock filter, especially when out on the road. This issue is like the dreaded which oil, oil filter, tire, etc is best. That said, Stromette votes for K&N but respects whatever choice someone else makes.
